AR23504-PKG | 2600–2800 PSI Unloader Package, GHA Adapter, Filter

AR23504-PKG by Annovi Reverberi — Complete VRC-B Unloader Plumbing Package | 2,600–2,800 PSI | 4.0 GPM | Forged Brass Body | Garden Hose Adapter | Stainless Inline Filter | Banjo Bolts | Chemical Injection Port

The AR23504-PKG by Annovi Reverberi is a complete unloader plumbing package engineered for professional pressure washer systems that need stable pressure regulation, inlet filtration, thermal bypass protection, and chemical injection capability — without the sourcing complexity of assembling individual components. Built around the proven VRC-B unloader valve (AR23504), the AR23504-PKG delivers a turnkey pressure regulation and plumbing solution rated for 2,600–2,800 PSI and up to 4.0 GPM — with a forged brass unloader body, aluminum bypass and inlet housing, stainless inline filter, garden hose adapter, banjo bolts with O-rings, and a chemical injection port, all in one organized kit. As part of Annovi Reverberi’s pump and unloader assemblies stocked and supported by WSHPWR, the AR23504-PKG is the correct specification for contractors, OEM builders, and service technicians who need a complete, compatible unloader plumbing assembly at the 2,600–2,800 PSI operating range.

The AR23504-PKG does not include a pump — it is a standalone unloader plumbing kit designed to complete the pressure regulation and inlet plumbing side of an existing or new pressure washer system. The VRC-B unloader body, GHA inlet adapter, stainless filter, banjo hardware, and chemical injection port are pre-selected for compatibility at the rated operating range. Open the box, connect the components, and the pressure regulation side of the system is complete.

Everything in the Kit — AR23504-PKG Complete Contents

VRC-B Unloader. GHA Adapter. Stainless Filter. Banjo Hardware. Chemical Injection. Nothing Left to Source.

• VRC-B unloader valve (AR23504) — the core of the AR23504-PKG. Forged brass body for high-pressure fatigue resistance and long service life. Manual pressure adjustment knob for dialing in working PSI for different tools and surfaces. Automatic bypass function safely redirects flow when the trigger gun is released — protecting the pump from dead-head pressure and heat buildup. Rated for 2,600–2,800 PSI and up to 4.0 GPM.
• Aluminum bypass/inlet housing — corrosion-resistant and lightweight for compact skid or cart builds where overall system weight and package size matter. Provides the bypass flow path when the trigger is released, keeping the pump protected without back-pressure spikes.
• Garden Hose Adapter (GHA) — fast connection to standard garden hose water supplies. The GHA inlet allows the AR23504-PKG to connect directly to a standard residential or commercial water supply line without additional fittings or thread adapters at the water source.
• Stainless steel inline filter — traps debris, sediment, and scale before it reaches the pump inlet or valve seats. Protects both the VRC-B unloader valve and the downstream pump from particulate damage. Cleanable and serviceable in the field without special tools.
• Banjo bolts with O-rings and seals — all critical plumbing joints use banjo bolt and O-ring sealing for leak-free, service-friendly connections. When service is eventually required, O-ring replacement is a low-cost, fast procedure that restores full sealing integrity without replacing hardware.
• Chemical injection port — integrated into the AR23504-PKG unloader assembly for drawing detergents directly into the high-pressure water stream. Connects to a standard chemical suction line and injector for downstream detergent application without a separate external injector tee.

VRC-B Unloader — Pressure Regulation at the 2,600–2,800 PSI Range

Forged Brass Body. Manual Adjustment. Automatic Bypass. O-Ring Serviceability.

• Manual pressure adjustment for job-matched output — the AR23504-PKG’s large pressure adjustment knob lets operators dial working PSI up or down for each cleaning task. Surface cleaners, lance work, and specialty accessories each benefit from matched pressure — the VRC-B manual knob puts that adjustment at the operator’s hands without tools or system disassembly.
• Automatic bypass protects the pump — when the trigger gun is released, the VRC-B unloader automatically redirects pump flow through the bypass circuit. Pump output continues to circulate rather than dead-heading against closed valves — preventing the pressure spikes and heat buildup that shorten pump packing, valve, and plunger service life. The bypass is automatic and instantaneous at every trigger release.
• Forged brass body for sustained high-pressure duty — the VRC-B’s forged brass construction resists the pressure cycling fatigue that affects cast alternatives over time. At 2,600–2,800 PSI across contractor and commercial cleaning duty cycles, the forged body maintains dimensional stability and thread integrity across years of service.
• O-ring sealing for field serviceability — all critical joints in the AR23504-PKG use O-ring sealing. When O-rings eventually require replacement — the expected maintenance event, not a failure — the process is fast, inexpensive, and requires only standard hand tools. AR North America stocks O-ring service kits nationally through authorized distribution channels.
• Stainless inline filter for inlet protection — sediment, scale, and debris in the supply water are the most common source of premature valve seat and pump seal wear. The stainless inline filter in the AR23504-PKG intercepts particulate at the inlet — before it reaches the VRC-B valve seats or the downstream pump. Clean and inspect the filter regularly to maintain consistent flow and pressure at the unloader inlet.
